A Stochastic Geometry Analysis of Inter-cell Interference Coordination and Intra-cell Diversity
Xinchen Zhang, Martin Haenggi
Inter-cell interference coordination (ICIC) and intra-cell diversity (ICD) play important roles in improving cellular downlink coverage. Modeling cellular base stations (BSs) as a…
